Police hope to nab attacker before he strikes again.
After Texas police took the search for a serial rapist to the national level with America's Most Wanted, tips from the public have been pouring in.
The man has been targeting alumnae members of the Delta Sigma Theta Sorority in North Texas over the last year.
"Since that time we've had a lot of tips come in to our tip line and through Crimestoppers as well," said Officer David Tilley, with Plano's Police Department.
Investigators say most of the leads have come from individuals in North Texas where the man has been active.
Since November 2010, the man has been accused of breaking into the homes of four women, all members of Delta Sigma Theta Sorority.
Of those, the man is accused of raping three.
"If we don't get this guy caught and the media attention winds up dropping down on this there's going to be a lot more opportunity for him to actually commit the offense because a lot of people will be letting their guard down," said Tilley.
As many as five months have passed without an attack, and Plano police are concerned that the man's target might have changed.
They believe that he may already have his next target under surveillance.
A task force consisting of three departments is working around the clock to identify and arrest the man, but police know the clock is ticking.
"We don't want anymore victims on this deal so we're trying to make everybody as alert as possible on this and this doesn't limit it to just even being sorority it could be anybody," said Tilley.
